Both would hurt, but they say there's only a very slight chance of dying from a lightning strike anyway, though there's little larger of a chance of being f'd up for life, like brain dead or something, but still better chance of surviving than a shark attack. My Dad was struck by lightning and lived, my uncle was also struck by lightning and lived. And I met a girl the other day that was struck by lightning and lived, I believe I may also know one other person who lived through it, not sure though.

Struck by lightning would be a much cooler thing to brag about than a shark bite. There's a very rare chance to be struck by lightning, so I guess if you find being hurt cool, it would be cool you were the one of a very small amount of people who have been struck. A chance of being bitten by a shark is quite large if you go to the ocean.
